Test of a Communication Interface Connected to an Analog Telephone Line

Abstract: a method for testing a communication interface connected to an analog telephone line including two electrical wires, the method including the following steps: if it is detected that the communication interface switches into an off-hook state, collecting measurements acquired by the communication interface; if the measurements have nominal values, implementing a processing operation. during the processing operation, if it is detected that the communication interface is maintained in the off-hook state for a predefined duration, ordering a complementary test on the telephone line; if the test reveals a fault in the analog telephone network, issuing an alarm, and otherwise repeating the processing operation.
